Some people love Silicon Oasis and have actually asked to be moved there from other properties, some people would rather leave the company than live there. It is a very personal thing, where we like to live. However, remember that wherever the company put you is where you remain until and unless the company decide to move you. The utilities allowance will only rent you a one bedroom flat in a nice area, it is about 50% of the rent you would need for a nice villa before you look at electricity and water bills and the housing fee/tax (5% of the annual rent paid to the government). If you wanted to buy it won't cover the mortgage on anything much really.
It would be a terrible thing to turn up at Silicon Oasis on your first day at Emirates and find out that your wife and family hate it....
